I get my tilt level and zoom setting to what I like but as soon as I come across a roundabout the settings change. I have turned off the 'Zoom In' function and the 'Overview' function but the view still changes.

Is there anyway I can fix my perfect map view settings?

i have noticed this too except that it is not NEVER. i have not been able to figure out why sometimes it will save the tilt settings and sometimes it will not. just keep trying every now and then and it should finally save it for you. try turning off some of the nav features like AUTO ZOOM or whatever its called and see if that helps.

Yep, tried turning off the autozoom.

Maybe there's some default settings that it reverts to when you've gone through a roundabout, these need to be changed. I have hacked the tilt level so I can tilt enough to see the sky, maybe that's where my problem is.

Any help appreciated.

Thanks
